Seriously I don't know whether I should take this as a good news or bad news. While it opens up possibilities or would rather say opportunities to have new investors getting into bitcoin pretty quick, what I worry is that when there is too much fund pouring in, the price will go up very fast....in fact toooo fast. If it can go up fast, it can also go down at similar speed or rate. I just hope that is not the case.
Take it as good news, derivatives can have a price smooting effect since you do not have to trade the underlying directly. And they provide protection against price volatility without having to sell the underlying.
